Show HN: Nemorize – AI-powered spaced repetition for learning anything

I built Nemorize to solve my own frustration with flashcard apps: spending hours creating cards instead of actually learning.

What it does: Describe what you want to learn (e.g., "Norwegian A1 vocabulary" or "React hooks") and AI generates a complete lesson with 15-25 questions

Spaced repetition system tracks your progress across 9 mastery levels (Apprentice → Burned)

AI evaluates open-ended answers for language courses and conceptual questions Works on mobile and desktop

Tech stack: F# / ASP.NET Core backend Vanilla JS frontend and lit SQLite database

Claude for AI generation and evaluation

What makes it different: AI generates both the lesson content AND the flashcards, not just one or the other

Stricter evaluation at higher mastery levels (Guru+ requires correct spelling/grammar for language courses)

No subscription wall for core features

I'd love feedback on the learning experience and any rough edges you find.
